摘要
文章通过给出逻辑函数几种形式之间的简单变换关系,运用卡诺图将逻辑函数的化简与变换结合起来,克服了代数法实现逻辑函数变换的繁琐与不足,丰富了变换的方法和途径。卡诺图法尤其有利于含有无关项逻辑函数的变换,并能提高数字电路的教学效果和设计效率。
The paper presents the simple relation to several forms of logic function, and a method using the Karnaugh Map for the combination of simplification with transformation, which can overcome the difficulties of the algebra method, and enrich the methods of transformation. This method is particularly suitable for transformation of the logic function with some irrelevant terms. Therefore, this paper improves the teaching effect and designing efficiency of digital circuits.
